HARVEY L. HOPKINS, OF CHICAGO, ILLINOIS, ASSIGNOB TO THE HOPKINS PATENTCOMPANY, A CORPORATION OF ILLINOIS.

IVIOWER OR HARVESTER.

To all whom it may concern:

Be it known that I, HAnvEY L. HOPKINS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mowers or Harvesters, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in mowing machines.

In some respects it pertains more particularly to improvements inmachines of the sort which transmit the power to the cutting apparatusthrough devices such as I have shown in my Patent No. 645,395, grantedon the 13th day of March, 1900; but in some other respects the novelfeatures of contraction herein presented are applicable to use in mowersor harvesters of other sorts.

1, 1, indicate the ground wheels. are mounted upon the axle 2.

3 indicates the initial wheel of a train of gearing adapted to beconnected to the ground wheels by a clutch at 4, the engaging elementsof which can be thrown into and out of engagement as desired. Theseparts are, or may be, of any of the well known forms. Upon the aXle ismounted and to it is connected the main or draft frame which comprisesthe tongue 5 and the sleeve 6, the latter having a forward projectingsocket 7 to receive the tongue and also having arms or projections forreceiving and holding several of the parts of the machine, such as theseat 8 fastened to the socket extension 9.

The gear frame is indicated as a whole by 11.

10 is a tube or sleeve extending forward from and preferably castintegrally with the These transverse axle sleeve 6. The gear frame has aspindle part 12 which is fitted in the tubular bearing 10. It extendsforward therefrom and is formed with a box or cavity at 13 to receivethe gear wheel 1-1, secured to the shaft 15, mounted in the bearings 1G,17 in the frame or support 11.

12 is a groove in the periphery of the spindle part 12 and is adapted toreceive the end of the stop screw 12a which serves to hold the spindlepart 12 in the proper position within the tubular bearing 10. The groove12 permits the rocking of the said spindle within the said bearing whenthe stop screw is set to prevent the removal of the spindle from thebearing.

The shaft 15 has a sprocket pinion 1S, which is connected by a chain 19to the initial transmitting wheel. 3, which in this case is a sprocketengaging with the chain.

The section 11 of the gear frame extends forward of the wheel 1i andsupports a transversely mounted shaft 20, provided with a gear pinion 21meshing with the aforesaid wheel 1st. This shaft 2O carries the crankdisk 22 at one end. and at the other end is fastened in position bymeans of the nut 23, which is secured by the lock 24, consisting of thedisk 25 with a row of perforations 26, together with the wire 27, thebent legs 28 of which are adapted to be inserted into one or another ofthe apertures 2G. The section 11 of the gear frame extends still fartherforward and has a head 29 and a spindle or short stud-shaft 29El at itsfront end, the stud shaft projecting horizontally forward. By means ofthese the front end of the gear frame is connected both to the tongueframe by the tie rod 30 and to the cutter frame by the brace rod 81, aswill be more fully described. This brace rod 31 forms part of what maybe regarded as a bracing or coupling frame represented asa whole byPreferably it is formed by bending a suitable bar of wrought metal insuch way as to provide the aforesaid part 31 with a long rearwardlyinclined part 33 and a longitudinally arranged connecting bar 84. Thepart 33 is at its rear end supported flexibly at 35, that is to say,supported in such way that the part 34 and the devices connected with itcan rise and fall vertically around an axis extending from the attachingpoint at 35 to the stud shaft or spindle at 29, this axial line beingsubstantially in one of the vertical longitudinal planes of advance ofthe machine.

The cutting apparatus comprises as usual the bar 36, finge or guards 37and a knife bar 3S. The bar 86 extends from the shoe 39 at the inner endto a shoe at the outer end, which can be of the ordinary sort.

The shoe 39 'is connected to the frame 32 by means of the supportingsleeve 40, which 65 fits loosely on the front transverse brace rod B1.This sleeve can be rocked around the bar 31 by means of the lever 41 andconnecting parts. The lever is pivotally mounted at 42 on a support 43cast with or secured to the axle sleeve G, and the short lower end ofthe lever is connected by the link 114 to a crank arm L15, which extendsup from the sleeve L10.

The link e141 and the crank arm -15 are connected together in a peculiarmanner so as to accomplish an importamt purpose. lt is desirable to havethe cutting apparatus, including the inner shoe, the outer shoe, and thebars supported thereby, mounted in such way that it will automaticallytilt or vibrate vertically around a horizontal axis parallel to thelongitudinal lines of this apparatus. By so mounting it, it becomespossible for the shoes, and even for the guard-fingers, if they come toany obstruction or rise in the ground surface, to tilt upward at thefront, permitting them to slide over such obstructions, and withoutcausing excessive strains upon this part of the machine. One of theseveral ways for accomplishing this is illustrated in the drawings,which show the manually-operated tilting mechanism as being so connectedto the cutting apparatus that the operator can apply power thereto fortilting it in one direction, and can also prevent it from moving in theopposite direction beyond a predetermined position. The draft link 414passes loosely through a relatively enlarged eye or aperture in thecrank 45, and on the front side of the latter has a stop or abutmentdevice, at 45a, of such dimensions as to prevent it from slippingthrough the aperture although the link rod 44 itself is susceptible ofsuch slipping.

lt will be seen that the cutting apparatus can rock around the axis ofthe hinged sleeve 40, while the link 114 is stationary, the crank arm4:5 slipping backward and forward along the rod. If the shoes orguard-fingers should come to a knoll or rolling` place ou the groundsurface, they rise up at the front without impediment and pass over it.The tendency for the cutting apparatus to thus tilt or rise upward atthe front is checked or controlled by the draft of the horses.

85 is a swinging bar or plate pivoted at- SG to the tongue 5, and tothis is attached the double-tree 87. 8S is a link flexibly connected tothe lower end of the bar or plate 85, and also to a crank arm 89 formedwith or cured to the sleeve 40. Through these connections a part of thedraft of the team transmitted to the cutting apparatus in such way as totend to hold it in operative position; yet the stress from the draftdoes not cause such a rigidity as to prevent the bar from tiltingupward, as above described. The draft rod S8 is connected to the cuttingapparatus at a point just high enough to hold the guards down by thedraft. In other words, the finger bar is held at a position closelyapproaching one of over-balance when normally at work.

The guards can be held at any desired position; that is, they can beprevented from dropping forward beyond a predetermined position bylocking the tilting lever 41 at the proper point on its ratchet segment.The tilting lever is available for use in the ordinary way inregulating` the height of the cut, but the guards and cutting apparatusare not, in this machine, adapted to be forced downward at the frontpositively by any action of the tilting lever 4l, such downward tiltbeing given by the draft of the team through the connections abovedescribed.

The brace frame 32 and the parts supported by it can be raised andlowered either by means of the foot lever 46 or the hand lever 47. Theselevers are both connected to an intermediate rocking device 48 pivotedto the tongue and having the arm 49 connected to the link 50, which atits lower end is connected mediately or immediately with the parts to belifted or lowered. T prefer to connect the link to a gag lever, which isindicated by 5l. It is pivoted at 52 to the coupling` sleeve 40. Infront of its pivot it is formed with two arms, one shown at 53 and oneat 54. The arm is arranged and adapted to bear upon a shoulder on theshoe 39, this shoulder lying on the outerside of the hinge bar 56 of theshoe. This hinge bar is seated in the hinge sleeve or tubular bearing 57on the shoe and is mounted on a longitudinal approximately horizontalaxis. The arm 54 of the gag lever 5l extends upward and across more orless of the part 34' of the brace frame 32. These parts are so arrangedthat when the upward stress is exerted byV means of the lifting devicesit is first transmitted to the shoe 39 through the lower short arm 53bearing upon the shoulder on the shoe, the resultbeing that the earlierpart of the lifting impulse causes the cutter bar to rise at its outerend a short distance and the sagging down of that end is overcome. Afterthe outer end of the cutting apparatus has been lifted as far asdesired, this part of the machine as an entirety, and the inner part ofthe brace frame, together rise bodily as the lifting stress from thefoot lever 46 or the hand lever 47 continues.

he foot lever 46 is pivoted at 4Gb to ears cast on the axle sleeve 6. Ata point 46a above its pivot 46b it is connected to a draft rod 59, whichin turn is connected to the rocking device 4S. The latter connection iseffected by means of an ear 60, having a relatively large aperturethrough which the rod 59 passes. The rod is prevented by means of a stopdevice, rsuch as a washer and pin or nut, or the like at 6l; but the ear60 can move away from the stop device, which is desirable when therocking plate 48 is being operated by the hand lever 47. This lever isrigidly secured to the rock plate 48 and extends to a point within reachof the driver who occupies the seat at S. He has his option of pressingdownward on the lever 46 with his foot and drawing backward on the rockplate 4S to lift the cutting apparatus, or to accomplish the lifting byhis hand through the lever 47. When he employs the foot lever 46, thehand lever will move backward simultaneously with the foot lever. But,on the other hand, if he employs the hand lever alone, t-he foot leverafter reaching its stop, remains stationary as the rod 59 slips throughthe enlarged aperture in the ear 60.

To assist the operator in lifting the cutt-ing apparatus, use is madeo-f a spring 62. At its lower end it is secured to a hoo-k or projectionon the frame, and at its upper end it is connected adjustably to one oranother of a series of hooks 63 on the lever 47. The line of the spring,when extended in relation to the line running from the lever pivot tothe point of attachment of the spring to the lever, is so disposed thatwhen the cutting apparatus is down, in normal working position, theforce exerted by the spring acts substantially along the line of thelever 47, but in the movement of the lever backward and downward thelongitudinal axial line of the spring leaves the lever and the angulardistance between these parts is increased.

By examining the drawings it will be seen that the foot lever and theparts connected with it are so related that when the operator pressesdownward upon it he brings the draft rod 59 into such position that theline of its draft is exerted nearly on the line which runs from the ear60 to the pivot 46" of the foot lever. At this time the power of theoperators foot has the utmost eiiiciency and he can control the positionof the cutter frame with great accuracy and ease of movement. There isat no time a positive lock and in this respect the mechanism is superiorto others with which I am acquainted which have parts which provide suchpositive lock and which therefore require attention on the part of theoperator and also the exertion of power to an extent not desirable. Inthe present machine he has accuracy of control and by merely removinghis foot can instantly lower the cutter frame as desired.

The sickle 38 is reciprocated by the crank disk 22 and the pitman 64.The pitman is formed with the shank part 65 and with l cups at the endswith cavities, spherical or from drawing backward through the ear 60 lpartly spherical and adapted to it corresponding balls. At the crank endthe cup or socket is formed partly in one and partly in the other of twometallic bars 6G, which are secured to the shank 65, the sockets beingshown at 67.

(38 is the ball fitted in the sockets at G7. This ball is formed on theend of a pin or bolt 69 which has its bearing in the crank disk. Thispin or bolt is not arranged on lines parallel to the axis of the shaft20, but on lines inclined thereto, the result being that there is avaluable compromise reached with respect to the lines of thrust exertedby the crank disk upon the pitman G4. The eccentricity of the ball G8 tothe axis of the shaft 20 insures the reciprocation of the pitman, theaxis of rotation of the crank sha-ft 20 being in a plane above that ofthe sickle bar, and consequently as the rotating ball (58 travels fromits uppermost point to its lowermost it relativelyT approaches thesickle bar and causes the pitman to thrust the latter outward, and as ittravels again to the uppermost position it moves to a position fartheraway from the sickle bar and causes the pitman to draw the sickle barinward again. But as the pin or bolt 69 is inclined on a line whichapproaches the axis of the shaft 20 in the direction of the sickle barthe thrusts exerted upon the pitman are much more advantageously appliedthan if the bolt or pin was parallel. The ball 68 has pins or trunnions70 diametrically oppo- 4 site to cach other, these extending throughapertures 7l in the socket bars 6G. The apertures are considerablylarger than the pins or trunnions, so that the pitman is free to takeall necessary positions, but the line of the pins 70 being at rightangles to the longitudinal line of the pin or bolt G9 they insure thatthe pitman shall be held from turning and from binding at the neck ofthe ball. It will be seen by reference to Fig. G that t-he pin 69, withthe ball 68 at its end, which constitutes the wrist-pin of the crank, islongitudinally adjustable, its end being screw-threaded and providedwith a nut and lock. This capability of adjustment of the wrist-pinmakes it possible to set the cutter bar accurately relative to the guardfingers and other stationary parts of the cutting apparatus. Of coursewashers 115 or equivalent devices will be employed to prevent loosenessof parts, such a washer being represented in Fig. G between a collarformed on the pin G9 and the face of the crank wheel that sets oppositethereto. At the knife end the pitman has metallic pieces 72 secured tothe shank 65 and in the ends of these the ball sockets 73.y 74, areformed.

75 is a ball secured to the knife bar and fitted in the sockets at 78,74. The ball proper is carried by a reduced shank 77 extending downwardfrom it to the knife bar. The socket part 74: has a downward extension76 of such dimensions as to fit upon or nearly reach the top surface ofthe knife bar 38. This part 7 G serves as a stop and holds the pitman inproper position and prevents it from turning about its axis.

It will be seen that both of the balls, namely that at 68 and that at75, have their shanks guarded against cutting or wearing and the edgesof the cup parts are similarly saved from wear, this being accomplishedat the crank end by means of the pins 70 in the apertures 71, andaccomplished at the knife end by means of the guard stop 7 G. Suchlegitimate wear as occurs from the sliding of the surfaces of the ballsand the sockets on each other I can take up by means of the clampingdevices at 7S and 79, these being bolts that pass through the socketpieces and are adapted to draw them together slightly when it is desiredto take up for wear.

The gear frame or support 11, as above described, is pivotally connectedwith the draft frame by means of the spindle-like part 12 fitting in thesleeve 10. It is capable of rotating within limits around the axis ofthis spindle l2. That is to say, the crank shaft 2O can be rocked aroundan axis transverse to its longitudinal lines. This axis, as will be seenby reference to Fig. 6, lies in a vert-ical plane that cuts the train ofspur gearing mounted in the rocking frame ll. When the inner shoe israised or lowered the rocking of the crank shaft and gear frame occurs,the motion from the cutter frame being transmitted to the gear framethrough the front bar 3l of the brace frame 32. This bar or arm 3l ispreferably connected to the gear frame by means of a fork 80 at the endof the rod. The head 29 at the front end of the gear frame or carrierhas shoulders 81, to which the legs 82 of the fork are secured by bolts83. The shoulders 8l lie one above and one below the axis of rocking ofthe gear frame. When the cutting apparatus is lifted and the brace frame32 swings up the legs of the fork 8O cause the gear frame or crank shaftcarrier to turn around its axis. And the parts last referred to alsoprovide a means for so adjusting the frame or carrier of the crank shaftaround its axis of rocking that the throw of the sickle bar can belengthened or shortened as desired. To accomplish this it is merelynecessary to suitably vary the positions of the legs S2 in relation tothe shoulders 8l to which they are fastened. This can be done in eitherof several ways. T prefer to employvsets of washers or liners 84, whichare held in place on the bolts S3 and clamped between the fork and theshoulders 81. If the distance of the upper fork leg from its shoulder beincreased by inserting more washers or liners the crank shaft will haveits operative end thrown and held relatively upward, and

at such time the throw of the sickle bar will be lengthened. On theother hand, if the upper fork leg be placed nearer to its shoul der 81and the lower leg be separated farther from its shoulder the crank shaftwill be turned and held in such way that it's operative end will bethrown downward somewhat and the reciprocations of the sickle bar willbe shortened. The carrier or frame for the crank shaft and the gear hasa bearing at its front end in the tie rod 30 through the end of whichpasses the spindle or stud-shaft 29a above described.

In earlier machines of this class which I devised the support for thecrank shaft and the gear was rigid in relation to the main frame, andconsequently when the cutter bar was lifted while in operation the throwof the cutters was reduced. This is not desirable under mostcircumstances, it being more advantageous to give the cutters the sameaction while they are operating whether they be in their lowermost lineor in a more elevated line, as when it is desired to continue cuttingwhile passing over a rise in the ground or over some obstruction, or bywhich it is desired to pass, without terminating the cutting work. Byhaving the crank shaft supported in gear frame rocked in the way .hereprovided I attain this end.

The downward and backward movement of the cutter lifting levers islimited, this being accomplished preferably7 by means of a stop 90secured to the inner side of the tilting lever 41, consisting of an armor shelf-like plate extending out horizontally across the path of thelifting lever 47. It has an upwardly turned flange or guard arm 91 whichassists in holding the lifting lever in place horizontally. The weightof the cutting apparatus tends to draw the lifting levers 46 and 47 backto their uppermost positions, but this can be prevented and the operatorcan cause the cutting apparatus to be held in elevated points by meansof the stop at 92, this being a short horizontally arranged projectionalso secured to the lever 41 and having downwardly turned guardflange orbar 93. Vhen the cutting apparatus is to be held in an elevated positionthe operator draws the lever 47 backward and downward until it strikesthe stop 90, and then pushes it laterally until it lies under the stop92, and then permits it to rise until it bears against the latter; and,after that, the cutting apparatus is held in the position shown in Fig.5.

Having, as above, set forth a form of mechanism embodying myimprovements I now call attention to the fact that in each of severalmatters there can be modification without departing from the essentialfeatures of the invention. Thus, as shown in Figs. 23 and 24, thestopping and locking parts last above described can be modified. Herethe horizontal stop plate 90a is supplemented by a hinged bar or plate90b pivoted at 90; and with it is combined a spring 90d which normallytends to throw the free end of the hinged bar upward. This guardsagainst sudden shocks or blows when the lifting lever 47 is beingdepressed. The swinging bar 90b is extended toward the lever 41 farenough to insure that when the lifting lever 47 is in the stop-loop at92a it shall be held therein by the spring so as to prevent accidentaldisplacement.

In Figs. 16 to 22, inclusive, I have shown a modification of the crossbrace or coupling frame and the connecting devices which join the innershoe of the cutting apparatus thereto, the frame being shown entire inFig. 28. In this case the part 34 of the brace frame is omitted, ithaving merely the two legs or arms SliL and 33a with asharp acute angleor bend at 81h. The longitudinal hinge bar of the shoe is carried by thecasting 40a, which is formed with a sleeve-like tubular part 40", thedownwardly extending webs 40C and the sleeve-bearing 40 for the shoehinge. This casting 40alis mounted loosely on the leg 31a of the crossbrace frame and is held from moving longitudinally thereon by means ofthe clevis lock 93. This comprises a collar 94 with a liange or bead 95acurved neck 96, and two arms 97 with perforations at 98. The flange orbead 95 is seated in a recess 99 formed in the end of the tubular partof the casting 40"-. 100 is a key having the body 101 and the curvedrecess 102, and the bolt aperture or socket 103. l hen in position' thiskey 100 is placed between the arms 97 of the clevis 93 and is held inposition by a bolt 104, passing through said arms and engaging with thekey. When all of the parts last described are connected up in the wayset forth and illustrated, the casting 40a is held against displacementlongitudinally on the bar 31a, but it is at the same time permitted toswing vertically as required. In assembling these parts and placing themin position on the frame 312L and 33a, the clevis 93 is fitted to thecasting 40a by slipping the Hange or bead 95 laterally into the socket99; and then they are slipped over the arm 31a of the frame until thebend 31b is reached; and then the key 100 is put in position and lockedby means of the bolt 104. At 105 a stud shaft is formed with the casting40'LL to receive the gag-lever.

In Figs. 25, 26 and 27, I have shown de` vices which can be used toadvantage for connecting the outer end of the front brace arm (31 or31a) to the rocking gear frame. Instead of making this front bar and thefork integral, as shown in Figs. 1, 3 and 6, they may be made separatefrom each other as shown in said Figs. 25 and 27.

The fork part is indicated by 80al and is formed with a semi-cylindricaltube or box part 106, and has apertures, as shown, at 10T, rlChe outerend of the frame bar 31a is secured to this forked part 80a by layingthe end in the half tube or box 10G, and pouring Babbitt metal aroundit, the brace bar being less in diameter than is the cavity in the fork.108 is a pin passing through and seated in the brace arm, and having itsends arranged to extend somewhat beyond the arm. The pin is covered byor lies in the Babbitt metal, and thus endwise displacement of the bracearm is prevented. Finally, the clamp screvfs 10) are secured in place,each of these havii'ig a curved part 110, which encircles part of thebrace bar, and a threaded leg lll which passes through the metal box orhalf-tube, and is tightly held in place by the nut 112.
